I also have a cast taken directly from the one on the original spinner that I love. Not sure if folk realise that the original Spinner logo is cast out of the same amber as the grips - seems like it was going to be backlit at some point - but ultimately it was painted over in silver.

I got a resin recast of one of the emblems from the guy that worked on the refit of the one for the Seattle MOST museum. Also got the cleaned up one from him. Very cool to know the original was amber. It was a tail light...lol
